Climate strike: School students from over 120 countries march to 'change history'

"We have proposed Greta Thunberg because if we do nothing to halt climate change it will be the cause of wars, conflict, and refugees", Norwegian politician Freddy André Øvstegård told global news agency AFP.

College and high school students in Boulder, Fort Collins and other cities across the country will step out of school for the strike.

New Zealand Prime Minister Jacinda Ardern, who has pledged NZ$100 million ($68 million) to reduce greenhouse gas emissions, supports to the student strikes, saying teenagers should not wait until they were old enough to vote to use their voice.

Some politicians have criticized the students, suggesting they should be spending their time in school, not on the streets.

"We only have a very short time to act on climate change, and [we] need to start now", Baines said.
